| Abstract: | Mesh surface deformation technology is the key in mesh model treatment of computer graphics.In this paper,the algorithm of point-constraint deformation based on multi-resolution had been studied,the algorithm can change body external surface shape by using Visual C++6.0.The shape results are displayed by OpenGL,the results show that the algorithm has high stability and smoothness,which can meet the needs of body's external surface reconstruction. |
